From Brabeeba: The main reason that motivated me to dive into granular materials again is revenge (Editor's note: For more on Brabeeba's competitive spirit, read his recent chapel talk). Three years ago, before coming to Peddie, I built a mini vertically-shaking table in order to show Faraday heaping, a periodic heaping behavior in a vertically vibrating environment. However, I failed (Otherwise I would not be doing it right now right? lol) This year, when I enrolled in Advanced Research Physics, I immediately decided this time I am going to clean the "stain" on me and be successful.
With increased knowledge and budget, Kenny and I built an humongous shaking table and researched literature to find some interesting experiments; for example, the use of index of reflection to make glass beads vanish, the use of the Brazil nut effect to automatically sort different particles by size, or building a 2D-chamber to research heaping and avalanche. All those things have been researched before; yet we also ventured to discover something new. Right now, our main objective is to research in the equilibrium between diffusion and gravity in a tilted shaking environment. Hopefully, by the end of 2014, we can finish our paper and submit it either to a science fair or a journal.
From Guilbert: The videos are designed for the general public - curious folks, armchair scientists, kids, etc - as the main audience. But also a part of the audience is science students and teachers who may be in an environment - a remote school, or a school with limited resources, or perhaps homeschoolers - where there aren't the funds and/or the expertise to do experiments like this. The videos can be used to learn or teach physics in their own setting. Each video includes a section at the end that dives more deeply into the physics underlying what the video shows. Those parts are completely skip-able for most viewers without losing any of the ideas from elsewhere in the video.
